LINING FOR ENGINE-CYLINDERS.

' Specification of Letters Patent.

Patented Feb. 7, 1911'.

' Application filed June 28, 1910. Serial No. 569,284.

Be it known that I, EINAR N. SonENsEN, a citizen of the United States,residing at Athens, in the county of Bradford and State of Pennsylvania,have invented certain new and useful Improvements. in Linings forEngine-Cylinders, of which the following is a specification.

My invention relates to improvements in linings for engine cylinders,the object of the invention being to provide a lining for enginecylinders, particularly adapted for the cylinders of internal combustionengines, to take the wear of thepiston and which may be reinoved andreplaced when worn.

A further obj ecu is to provide an improved lining which may be used inworn cylinders after boring the latter, hence enabling discardedcylinders to be utilized.

A further object is to provide an improved lining so as to beable to usealuminum in the casting of cylinders. 1

With these and other objects in view, the invention consists in certainnovel features of construction, and combinations and arrangementsofparts, as will be more fully hereinafter described and pointed out inthe claims.

In the accompanying drawings: Figure 1, is a view in longitudinalsection illustrating my improved lining in a; cylinder for engines ofthe internal combustion type. Fig. 2, is asimilar view illustratingmyimproved mechanism for removing the lining. Fig. 3, is anenlarged viewin end elevation of the bar 6, and Fig. 4, is a view in section thereofillustrating the position of the oper ating rod 5.

1, represents acvlinder for internal combustion engines, and 2 is myimproved lining snugly fitting the cylinder but prefer ably terminatingshort of the inner closed end of the cylinder, leaving aspace devoted tothe exploding of the gases, as no lining is needed at this point. Thelining 2 projects outward beyond the open end of cylinder 1, andithelatter at its open end is provided with a circular groove 3 to receivean annular flange ,et around the out-side of lining 2, so that when thecrank casing 7 is secured against the end of cylinder 1, by means of thebolts 8 and screws 9, the flange 3 will be confined and the lining 2held against any possibility of longitudinal movement.

a cross bar 6, and is provided at its inner end with a head 13 locatedin a recess 14 in the bar 6. The ends-of the'bar are rounded to conformto the curvature'of the cylinder, and recesses 15 are provided in theends of bar 6 to receive the end of lining 2, and bear against theend ofthe lining to draw the sagpc out of the cylinder as will be hereinafterexplained.

Rod 5 is screw-threaded throughout a portion of its length and a nut 16is located on the threaded portion of this rod and bears against fork10, so that when the nut is turned, it will compel the rod to movelongitudinally. i

To enable bar 6 to be inserted through the lining, one wall of opening12 and one wall of recess 14 are inclined, so that the bar 6 may bepositioned at an angle to rod 5 while being moved through the lining,and when when the latter is drawn outward, the recessed ends 15 of bar 6will engage the inner end of the lining. When in this position,

the turning of nut 16 will cause rod 5 and bar 6 to move outwardly anddraw the lin ing 2 out of the cylinder.,

Various slight changes might be made 1n the general form and arrangementof parts described Without departing from my invention, and hence I donot limit myself to the precise details set forth, but consider myselfat liberty to make such changes and alterations as fairly fall withinthe sp1r1t and scope of the appended cla1ms.

' Having thus described my inventlon, what I claim as newand desiretosecure by Letters .Patent is 1 1. ,The combination with an enginecylinder having a closed end and a circular groove in its open. end, ofa lining fitting the cylinder and terminating short of the closed end,an annular flange around'the outside of the lining located; the groovein end and an open end, and an annular inthe open end of the cylinder,and means I of the cylinder around the projecting end confining theflange in the groove, substanof the lining, and confining the flange oftially as described. the lining in the groove, substantially as de- 152.
